SYSTEM
[0001] .
FIELD OF THE INVENTION
[0002] This invention relates to a personal thermal control apparatus. More
particularly,
a effective and long term use personal thermal control apparatus.
BACKGROUND OF INVENTION
[0003] In cold or hot climates, it may be desirable to provide heating or
cooling for
personal comfort to an individual. For example, personal heating or cooling
may be
desired during activities such as skiing, camping, hiking, fishing, hunting,
working,
athletic activities, military and the like. In some instances, application of
heating or
cooling to injuries, sore muscles or in joints in cooling the blood to
minimize brain
damage, and the like may provide a therapeutic effect.
[0004] There are several known prior art apparatuses for providing personal
heating
and/or cooling for an individual. For example, U.S. Pat. No. 5,766,235, U.S.
Pat, No.
5,514,170, and U.S. Pat. No. 6,514,279 provide various personal apparatuses.
Prior art
heated outerwear may utilize less efficient resistive heat and delivers the
heat to areas of
the body like the midsection or chest area. While heating the midsection or
chest area

provides heating, it does not effect a core body temperature change. Core body
temperature changes are measurable orally by thermometer.
[0005] Personal thermal control devices, such as described herein, provide
body
temperature change. The thermal fluids or gels that may be utilized in other
devices
allows for a limited duration that the device may be utilized until the
thermal energy is
exhausted. Further, immediately upon use, the temperature of the device
steadily
increases or decreases as the thermal gel is heated or cooled by the user's
body.
Recharging the device for cooling may require placement in a freezer for a
significant
amount of time or replacement with a substitute thermal storage packet that
has
previously cooled. Other known devices that utilize electronic heating have
short
running times and do not efficiently heat the body.
[0006] The personal thermal control apparatuses and methods discussed herein
provide
heating and/or cooling utilizing thermal module, These apparatuses are
positioned at the
inner wrist pulse point area and or the inner ankle pulse point area in close
proximity to
major vasculature located at the skins surface and externally delivers
constant thermal
energy, hot or cold to a thermal plate designed to maximize surface area
contact with the
blood vessels near the apparatus that transporting blood in both directions at
core body
temperature. Heat transfer occurs with the blood, and the circulatory system
distributes
blood throughout the body. The circulation of heated/cooled blood provides the
desired
counter active change in core body temperature desired by the wearer. These
personal
thermal control apparatuses provide for efficient electric operation to reduce
size and
power requirements. The apparatuses provide improved operation time. In some

DETAILED DESCRIPTION
[0023] Refer now to the drawings wherein depicted elements are not necessarily
shown
to scale and wherein like or similar elements are designated by the same
reference
numeral through the several views.
[0024] Referring to the drawings in general, it will be understood that the
illustrations are
for the purpose of describing particular embodiments of the disclosure and are
not
intended to be limiting thereto. While most of the terms used herein will be
recognizable
to those of ordinary skill in the art, it should be understood that when not
explicitly
defined, terms should be interpreted as adopting a meaning presently accepted
by those of
ordinary skill in the art.
[0025] The personal thermal control apparatuses and methods discussed herein
provide
for effecting core body temperature changes in humans for long durations. The
apparatus
may electronically provide heating or cooling to a focused specific area of
the human
body. As a nonlimiting example, heating/cooling module may be strategically
positioned
directly over major blood vessels and capillary beds located at the pulse
points of the
wrist, ankle, or other areas of the human body. The average core body
temperature for
humans can be raised or lowered effectively through thermodynamic heat
absorption by
the blood that flows through the major blood vessels and capillaries located
just under the
skins surface with-in a specific surface area located at the pulse points of
the wrist and
ankle areas.
[0026] In one embodiment the heating/cooling module may be a thermoelectric
element.
Thermoelectric elements allow an electrical potential to create a temperature
difference
8
SUBSTITUTE SHEET (RULE 26)
CA 02839762 2013-12-17

PCT/US2012/042950
or a temperature difference to create an electrical potential. The apparatus
may utilize
thermoelectric element(s) for heating/cooling by applying a voltage to the
element. The
polarity of the applied voltage provided to the thermoelectric element
determines whether
heating or cooling is provided. In some embodiments, the heating/cooling
module may
also provide a resistive heating element.
[0027] Personal thermal control apparatuses provide the ability to effectively
raise or
lower human core body temperature on demand. Men, women and children of all
ages
may use personal thermal control apparatus in their daily lives to provide
heating or
cooling as desired for long durations of time. Personal thermal control
apparatuses may
be incorporated into apparel, outerwear, coats, jackets, sweaters,
windbreakers, shirts,
pants, shorts, wristbands, footwear, combinations thereof, and the like. The
personal
thermal control apparatus is suitable for a wide range of activities, such as
sports,
recreation, work, camping, fishing, hiking, and military use. The personal
thermal
control apparatus may also be utilized in medical applications requiring hot
or cold
treatments. For example, the apparatus may be utilized to fight inflammation,
high fever,
stabilization and minimization of brain damage after strokes, head injury, or
the like.
[0028] The personal thermal control apparatus may utilize heating/cooling
modules to
allow for significantly increased operating duration. Further, the personal
thermal control
apparatus is capable of maintaining consistent temperature throughout use.
Various
features of the device provide improved functionality that allows the device
to efficiently
reduce or increase a user's core body temperature. By using a thermal module
to heat or
cool a thermal plate or similar size, effective heating or cooling for the
wearer can be

realized using a very low current. The low power requirements of the apparatus
allow it
to operate for longer durations (e.g. 24 hours or more) than prior art
apparatuses. By
incorporating photo voltaic/solar power, the duration of operation can be
extended even
further and may potentially allow for perpetual operation. Perpetual or
extended
operation is particularly useful when access to a plug-in power source is not
available.
For example, perpetual or extended operation may be highly beneficial in
military
applications.
[0029] FIG. 1 is an illustrative diagram of the electronic components of a
personal
thermal control apparatus. The apparatus may provide a power source 10,
controller 20,
thermal module(s) 30-1, 30-2, 30-n, I/0 interface( s) 40, and power input port
50. Power
source 10 provides electric power for the apparatus. Power source 10 may be an
external
source, solar panels, batteries, rechargeable batteries, and/or the like.
Nonlimiting
examples of suitable batteries may include NiCd, NiMH, and Li-ion batteries.
In one
embodiment, the battery 10 may be a 3.7V. The battery may also be a 2,500 mAh
Li-ion
battery. Power source 10 is coupled to controller 20, which routes power to
thermal
module(s) 30 or 1/0 interface(s) 40 and manages charging of the battery.
Controller 20
manages various operations of the apparatus such as, but not limited to,
heating/cooling
management, charging, operation modes, communication with I/0 interface(s),
and the
like. In some embodiments, heating/cooling management may be governed by
sensors
that constantly monitors core body temperature of the wearer, and the
controller 20
adjusts to heating or cooling as needed to counteract adverse climate
conditions.
Controller 20 may be a microprocessor, processor, CPU, integrated circuit, or
a
SUBSTITUTE SHEET (RULE 26)
CA 02839762 2013-12-17
WO 2012/174528
PCT/US2012/042950
combination thereof that may be programmed for operation of the apparatus as
discussed
herein. For example, controller 20 may provide functionality such as battery
monitoring
(including voltage and current monitoring), battery status indication (e.g.
low battery or
charging), function status indication (e.g. charging, cooling, or heating),
built in charging
circuitry, and the like.
[0030] Thermal module(s) 30 may provide heating and/or cooling in accordance
with a
voltage applied to the element by controller 20. Controller 20 may apply
voltage to one
or more of the thermal module(s) 30 as desired. Thermal module(s) 30 may be
strategically positioned to maximize efficiency of the heat transfer to a
user. For
example, the thermal module(s) 30 may be a Laird Technologies model number Cp
08,
63, 06L thermoelectric chip. In contrast to other personal thermal control
devices, the
thermal module(s) 30 operate using relatively small power source (e.g. 3.7V
battery). In
some embodiments, the thermal module(s) 30 may also provide a resistive
heating
element. I/0 interface(s) 40 allow the apparatus to be connected to interfaces
that allow a
user to operate, control, and/or manage the apparatus. I/0 interface(s) 40 may
provide
ports for external devices (e.g. cell phones, portable music devices, other
portable
electronics, Or the like). I/O interface(s) 40 may also provide control
buttons/interfaces.
For example, control buttons may allow a user to select modes of operation
(e.g. heating
or cooling); settings for the heating or cooling modes - low (50% power), mid
(75%
power), high (100% power); or the like. As another example, the apparatus may
include
control interfaces, a display, visual indicators, audio indicators,
combinations thereof, and
the like. In a non limiting embodiment, 1/0 interfaces 40 may include a on/off
button and
11
SUBSTITUTE SHEET (RULE 26)

WO 2012/174528
PCT/US2012/042950
visual indicators to indicate charging status, heating or cooling, operation
mode (e.g. low,
mid, high), power source the devices is utilizing, or the like. Charge port 50
may provide
a connector that allows the apparatus to be connected to an external power
source suitable
for charging. For example, the charge port 50 may be suitable for connection
to an AC
power source, 2.0 amp connector, USB connector, or any suitable electric
connector. In
some embodiments, charge port 50 may also provide coupling to portable power
source,
such as solar cells or an external battery.
[0031] In some embodiments, the apparatus may provide additional features such
as a
pedometer, clock, stopwatch, display, time/distance/steps information, GPS
location, blue
tooth or other communication technology and/or other features.
[0032] FIGS. 2A-2C are illustrative diagrams of an embodiment of a
heating/cooling
module 200 with a controller, power source, and user interface. In some
embodiments,
thermoelectric module 200 may be referred to as a main heating/cooling module.
The
heating/cooling module 200 may provide a thermal module 210, controller board
220,
battery 230, thermal plate 240, and user interface 250. Heating/cooling module
200 may
be strategically positioned directly over major blood vessels and capillary
beds, located at
the pulse points of the human body, such as the wrist and ankle area, to
efficiently
provide personal thermal control for a user. For example, the thermoelectric
module 200
may be utilized for a wristband that cools the blood vessels in the wrist of
the user.
[0033] Thermal module 210 may utilize electrical energy to heat or cool the
bottom
portion of the wristband. For example, thermal module 210 may be a
thermoelectric chip
that provides heating when a voltage is applied and cooling when a reverse
polarity is
12
SUBSTITUTE SHEET (RULE 26)
CA 02839762 2013-12-17
WO 2012/174528
PCT/US2012/042950
applied. Thermal module 210 may be metalized on the surface for improved
attachment
to optional heat sink(s). Further, in some embodiments, thermal module 210 may
also
provide a resistive heating element. Thermal module 210 may be electronically
coupled
to a controller board 220. Controller board 220 is a circuit board that
manages operation
of a thermoelectric apparatus, which may include controllers, processors,
memory,
modules, various electronic components, or combinations thereof. Controller
board 220
may also be coupled to a power source, such as a battery 230 or an external
power
source. Battery 230 provides a portable power source that powers the
apparatus. Battery
230 may provide sufficient power to operate up to 24 hrs. When battery power
is low, an
external power source may be utilized to recharge battery 230 and/or power the
apparatus.
[0034] The controller board 220 is coupled to the thermal module 210 and
battery 230.
Based on the settings selected, the controller board 220 controls the power
provided to
the thermal module 210. For example, when a desired temperature is selected,
the
controller may manage the amount of power provided to the thermal module 210
to
achieve the desired temperature. Additionally, the controller board 220 can
manage
additional features, such as battery charging, light indicators, or the like.
[0035] A controller (e.g. CPU, microprocessor, or the like) provided by
controller board
220 may controls the functions provided by the apparatus. These functions
include, but
are not limited, to battery connections, charging, power on off control, photo
voltaic
management, indicator operation, power provided to each thermal module, and
other
desired functions.

WO 2012/174528
PCT/US2012/042950
[0036] Plate 240 may preferably be in contact with thermal module 210 to
maximize
thermal transfer. Plate 240 may be formed from a material with high thermal
efficiency
or high thermal conductivity. For example, plate 240 may be copper or
aluminum. Plate
240 is positioned in housing 290 to minimize the distance between the plate
and the user.
For example, in the embodiment shown, plate 240 is positioned below controller
board
220 and thermal module 210 in a region that is closest to area that contacts
the user. The
plate 240 may provide a surface area specifically shaped to maximize the heat
absorption
for heating or cooling blood vessels. For example, plate 240 may be long and
thin to
maximize the contact area between the plate and the blood vessels in a user's
wrist or
ankles. In some embodiments, a thermal gel (not shown) that is in contact with
the plate
may be provided to aid thermal energy transfer. For example, a band
surrounding the
ankle or wrist may contain a thermal gel to further assist heat transfer to a
user. Further,
in other embodiments, a thermal gel may be substituted in place of a plate.
Similar to the
heat transfer plate, the thermal gel may be positioned at a desirable position
of a person's
body, such as on the wrist, ankles, or any other suitable position.
[0037] In a region above plate 240, insulator material 245 is provided to
minimize
undesired heat transfer from the plate to other parts of the module. Insulator
material 245
allows the majority of the heating or cooling to be absorbed by the user. Due
to the
temperature difference that is generated by thermal module 210, a side
opposite plate 240
may provide a different temperature. For example, when cooling is desired the
side of
thermal module 210 coupled to heat transfer plate 240 is cool, and the
opposite side is
hot. In order to dissipate the undesirable heat, a vent 255 in housing 290 is
provide to
14
SUBSTITUTE SHEET (RULE 26)
CA 02839762 2013-12-17
WO 2012/174528
PCT/US2012/042950
allow heat to dissipate out from the module. In some embodiments, a heat sink
(not
shown) may optionally be provided on top of thermal module 210 to aid heat
dissipation.
For example, when thermal module 210 utilizes components that generate heat
when
cooling, it may be desirable to provide a heat sink to aid heat dissipation.
[0038] The user interface 250 provides I/O interface(s) for the user to
operate the
apparatus. For example, in the embodiment shown, the user interface may
include a
charge port 260, button 270, and LED indicator 280. The charge port 260
provides
power to the apparatus, charges the power source, or both. The charge port 260
may be
connected to a suitable power source, such as a photo voltaic cell, AC power
source, DC
power source, or the like. Button 270 allows the user to control operation of
the device.
For example, button may be pressed to cycle through various modes of
operation, such as
low heating, medium heating, high heating, low cooling, medium cooling, high
cooling,
sensor mode to run off of the wearer's core body temperature and off mode. In
some
embodiments, it may be desirable to include additional inputs, buttons,
switches, or the
like. The I/O interfaces(s) may allow the apparatus to be turned on and off,
select a
mode, set the device to a desired temperature, and/or the like. The apparatus
may include
an LED indicator or display 280. In some embodiments, indicator(s) may be
substituted
with or include an LCD display, additional LEDs, light indicators, or the
like. The LED
indicator or display 280 may indicate when charging is occurring, when power
is low, a
temperature set by the user, an operating mode, whether the apparatus is
operating on
battery or external power, and/or the like.
SUBSTITUTE SHEET (RULE 26)

WO 2012/174528
PCT/US2012/042950
[0039] Heating/cooling module 200 is surrounded by a housing 290 to protect
the
module. Housing 290 may be formed in any suitable shape desired. For example,
housing 290 may be ergonomically shaped to comfortably fit around a user's
wrists,
ankles, or the like. Further, housing 290 may be shaped to maximize the
contact area
with the user's wrists, ankles, or the like. In some embodiment, housing 290
may be
waterproof. For example, housing 290 may be a polycarbonate skeleton or the
like. The
housing 290 and plate 240 may be ergonomically designed for comfort and to
provide
efficient thermal transfer. A thin polycarbonate shell may be snapped into
place over the
electronic components, and then the entire thermoelectric module 200 is over
molded.
For example, the over mold may be a sanoprene rubber like material for
durability,
waterproofing, and to protect the device from other elements including human
sweat. In
some embodiments, housing 290 may provide an area for sewing or attach the
thermoelectric module 200 to wristbands, apparel/outwear footwear, or other
accessories.
[0040] By providing external electronically generated hot or cold from the
apparatus to
specific blood vessel(s) via a shaped surface area through a thermal
conductive material
plate positioned directly over pulse points, on demand externally generated
hot or cold
can be utilized to make a user more comfortable. By applying heat or cold to
blood
vessels, the user experiences more effective cooling or heating than
apparatuses utilizing
heat or cold applied to areas that are not close to major blood vessels. For
example,
heating/cooling module 200 may be positioned on arteries and/or veins near the
wrist,
ankles, other parts of the body with one or more blood vessels, or a
combination thereof.

[0041] This new process may be utilized in several different consumer products
that are
focused on providing heating and/or cooling. The personal thermal control
devices may
be utilized in apparel (shirts, pants, shorts, etc.), outerwear (jackets,
sweatshirts, sweaters,
etc.), wrist bands, footwear, and other accessories.
[0042] The personal thermal control apparatus may be powered batteries,
rechargeable
batteries, solar power, external power sources, or a combination thereof. In
one
embodiment, the apparatus is battery powered. The apparatus may also provide
an input
port for receiving power from an AC or DC power source (e.g. to charge a
rechargeable
battery, to operate directly from the power source, or both) or photo
voltaic/solar power
cell(s). In one embodiment, the apparatus may utilize a 3.7V rechargeable
lithium
battery.
[0043] The apparatus may also provide one or more photo voltaic patches that
may be
utilized to generate power. For example, the patch may be sewn to sleeves or
shoulders
of apparel, provided on wrist bands, provided on footwear, or the like. The
apparatus
may be partially or fully powered by photo voltaic cell. The solar energy may
power the
device directly or may be utilized to charge and store power in the power
source. The use
of photo voltaic cells may provide extended operation time and may provide
operation in
areas where an external plug in power source is not readily available.
[0044] The photo voltaic cell patches may be positioned in locations that
maximize solar
exposure. The photo voltaic cells may be encapsulated in clear plastic and
over molded
in a rubber like material to create a lip that may be utilized to sew or
attach the device to
clothing or the like. A lens may be molded into the clear plastic cover to
magnify the

intensity of light onto the photo voltaic cell and may be used in conjunction
with a
holographic background to maximize reflectivity and in combination increase
the light
intensity and maximize the electrical current produced. Photo voltaic patches
may be
electronically coupled to the personal thermal control apparatus, such as by
wiring or the
like.
[0045] FIGS. 3A-3D are illustrative implementations of a heating/cooling
module that
incorporates a heat sink. Thermal module 210. controller board 220, battery
230. plate
240, and button 270 are provided as discussed in other embodiments, In some
embodiments, it is desirable to provide a heat sink 295 placed on thermal
module 210. It
may also be desirable to provide a fan 297 to further aid heat dissipation.
When thermal
module 210 is utilized for cooling, a first side of thermal module is cooled
and the
opposite side becomes warm Heat sink 295 increases heat dissipation from the
warm
side of thermal module 210. A top portion of housing 290 may be vented to
allow
through the housing to improve heat dissipation. The heat dissipation features
of the
thermoelectric module allow heat to be dissipated away from the module,
thereby
limiting or prevention absorption of heat by nearby components or the wearer's
body.
[0046] Thermal insulation material and thermal reflectivity may be used
throughout each
aspect of the design to maximize performance. Clear polycarbonate material may
be
used in the frame or skeleton. The skeleton may utilize infrared reflective
flecks molded
in the polycarbonate to maximize thermal reflectivity inside and outside each
device.
Thermal insulation material may be used through out each device to maximize
performance. Further, materials are selected to maximize product durability.
